USB-RS232-PCB Connector Pin Out and Mechanical details
Pad designation changed between Rev1 and Rev2 (see Figure 4.1)
R1 doesn’t exist in Rev2 design, the selection of power signal is done using either R2 (+3.3V) or
R3 (+5V), (see Table 4.2)
The LEDTX, LEDRX, PWREN and SLEEP are connected to the FT232R differently (see schematic)
The mechanical details of the PCB are shown in the following diagram Figure 4.2
